Patented May 25, 1954 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to new and improved razors and more particularlyto that type of razor known as a safety razor by reason of inclusion ofan interchangeable wafer-like blade which may be inserted and removedfrom the shaving vision of a shaving head which is provided withparticularly effective means for reducing the sliding frictional contactbetween the non-blade portion of the razor and the face of the user.

Another purpose is to provide an improved shaving head which may beformed, in large part, from sheet metal by stamping and bending thesame.

Still other features of the invention reside in the provision of alever-operated hood member for the shaving head, of spring engagementmeans for securing the lever arm in a quickly releasable position, andof guard means adapted to protect the engaged lever from accidentaldisplacement.

, Yet another object is to provide new and improved means for aligningand holding a blade in a safety-razor. g

It is within the province of the disclosure to improve generally, and toenhance the utility of devices of that type to which the inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination and amrangement of parts and in the details of corn struction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made within thescope of what is claimed, without departing from the spirit of theinvention.

Figure 21 is a side elevational view of my friction reducing rollershown mounted between opposing side wings which are seen in crosssection.

Having particular reference to the embodiments of Figures 1 to 4, myrazor is constructed of a generally elongated handle portion 20 and anupper head portion 22, which latter carries a dependent shank 24inserted in the handle or otherwise suitably secured thereto. Projectingupward from the shank is a generally annular disk section 26 from theupper edge of which extend a pair of outwardly diverging arms 22, 30which are bent forward (in relation to the upright disk 26 and shank 2to describe the sides of a generally triangular cutout or opening 32therebetween. Along the upper edge of the triangular cutout 132, the twoarms 28, 3b are bent downward and forward at approximately right anglesto form a fiat supporting ledge 3%. This ledge extends across the wholewidth of the head and has a transverse slot 36 cut forward partwayacross its center from the rear edge thereof.

Each end of the supporting ledge is provided with a turned down wing 38,ii which wings are disposed generally parallel to each other andtransverse to the longitudinal axis of the head. It will be observedthat the lateral wings extend beyond the edges of the supporting ledgeas both to the rear,wherethe-extensions ii form a mounting (as willbe'more fully described-hereafter) and to the front. The forwardextensions 44' are transversely apertured at it so as to journaljointlytherein, the mounting pin 48 of a facecontacting or friction-reducingroller b, the outer surface of the cylindrical roller being disposedsubstantially flush with (or extending beyond) the corresponding edge ofeach forward extension 44.

To facilitate mounting and removalof the roller .iilbetween-the bearingears ti t, the pin it may be longitudinally displaceable within theroller. Consequently in assembly the roller by itself may first belocated openings 48 and the pin then inserted jointly therethru; Byreason or" this construction, it is possible also to adjust the distancebetween the shaving edge of the blade, and the-roller. Since thisdistance is also a'measure of the minimum displacement of the blade fromthe shavers skin or of the closeness of ashavewhich one may'cbtain, itcan be controlled or varied by use of interchangeable rollers of'diiferent outer diameter. Accordingly with a small roller one obtainsaclose shave, whilewith a larger roller one getsa coarse shave. Andwith'the displaceable pin 48 mountingyone may simply push-the pin'out ofone aperture 46 with a pencil or the like, swing out the correspondingend of the roller and then withdraw the projecting pin androller jointlyfrom the opposite bearing ear ki. Another roller of dili'erent diametercan then be inserted with equal ease.

The upper edge of each side arm 38, 4t forward ofthe ledgeii l is formedwith a somewhat more downward inclined slant 52 than the ledge-itself,

and it terminates forward in an upwardly 'directed'abutting shoulder ornotch 5 1. The edge 52 and notch 5d of the opposing side wings 33, M arethus jointly adapted to align by contact therewith, a single edged blade56 (Figure 6) the cutting edge'58 of which is disposed to abut at eitherend against the respective notches 54.

To accommodate the present blade, as well as to promote frictionreducing contact with the shavers skin, the shaving head ischaracterized by atwo piece construction. The movable memberfifi of the'head is formed ofa generally inverted-L or hoe-shaped hood 6|, theupright or backing portion-S2 of which is rectangular and of somewhatless length than the collective-span of the twosupporting arms 28, 39. Aturned back ear E4 is disposed along eachlower corner thereof. Inassembly the ears are-disposed in juxtaposibetween the aligned 4 tionwith the corresponding inner faces of the respective rearward extensionsE2 of the side wings and are rotatably connected thereto by a hinge pinor rivet 66.

The forward or cover portion 6? of the movable hood generally overliesthe blade-supporting ledge 34. Its upper or outward face 38 is formedwith a longitudinal series of transversely directed alternating ribs andgrooves 1'6, i2 respectively, of generally equal width, the ribs beingadapted to contact the skin of the shaver so as to reduce the slidingfriction of the shaving head therealong. Mounted along the under face ofthe hood by'insertion in the centermost groove thereof,

is atransversely disposed fin i i having a pair of ba'ckwardly extendinglugs l8 (Figure 5) whichare received in corresponding apertures ll, 19(Figures '7, 11) formed in the rear portion 62 of the hood, the lugsbeing retained therein by being press fit, soldered or the like. Uponpivoting of the moveable head portion 65 upon the pins 63, the guide finE4 is disposed to move within the groove 36 of the supporting ledge '34and within a corresponding notch 30 cut inward from the rear or bluntedge of my blade Figure 6. The fin thus serves by frictional contactwith its sides, to mutually align the supporting shelf 34 (or stationarypart o'f'the head),'the blade 56, and the hood member Bl (or moveableart of the head).

Extending downward'from-the back 62 of the hood and bent angularly'outwardly so as to project forwardthru the-opening 32 between thesupporting arms 28, 38 is a dependent lever arm 82 carrying on its lowerend a-generally diskshaped thumb piece 34 and being then bent back toform a rearward projecting, resilient engaging hook St. The oppositedisk portion 25 of the stationary part of the head 22 is formed with amore-or-less central aperture 88 having 3, turnedback, lower engaginglip 90. Upon placing a blade 56 upon the supporting ledge 34 andpressing the thumb piece 85 in a rearward-direction, the spring'hook 86is pressed thru the aperture 88 and beyond the engaging lip 90 so as tooverlie the same. In this position the hood member 61 is clamped downuponthe'blade 56 so that the ends of its forward blade edge-iiiibeinglodged in the respective notches .56 of the lateral wings 38, 40," andits lower face being held in-frictional engagement with the positioningedges '52, the blade will be held securely in shaving position with itsrear edge 62 extending toward the inner face of the backBZ of themoveable head but not necessarily touching the same.

Locking means are provided against accidental displacement of theengaging hooktt from the disk aperture 88. For thispurpose a transversepivot pin 94. isvmountedin a corresponding aperture of the upper portionof the stationary disk 2%, bearing on opposite ends thereof enlargedhead members 96, 98. Between the rear pin head 58 and the rear face ofthe disk section 26 there is disposed about the shank of the pin 94 ahelical expansion spring 108, which may be anchored by a plate l 0 IAdjacent theopposite face of the disk 26 the pin carries-a rotatablewasher I522 having a dependent guard member ltd extending outwardtherefrom. f The guard member is formed with a neck portion me which isbent upward into a generally semi-circular shield lfiitwhich at itsfurther edges is-laterally extended orfiared on each side beyond thethickness of the neck.

It will be apparent accordingly that the shield I08 oan be swung fromone side to the :other upo'nthe pin 94 so as to expose the engaging hook86 from the rear of the razor and to allow it tube-pressed out of itssocket or aperture 88.- However'for locking it in its closed or-coveredposition, the plate I02 is formed with an inwardly pressed dimple IIO(Figure 3) adjacent its upper edge, which dimple in such position isreceived in a corresponding socket or depression I I2 of the disk 26.Accordingly it 'will'be seen that the expansion spring I serves tohold"the pin 94 m its innermost positionand thus retain the looking dimple- II0 in its socket,-consequently preventing lateral movement ofthe'dependant shield I08. Accordingly itwill require'a definite lateralpressure upon the shield, in one 'direction or the other, to dislodgethe plate-I 02 from its engaging position, thus turning the same on themounting pin I04 and exposing the spring hook 86 for manual ejection. I

Another method of mounting the guard member I04 is particularlyillustrated in Figures 7 to 10; Inthis embodiment a-imof'unting pin H4is provided with o osing"fiensed' h ad meriibere H6, H8 onopposite'ends. 'A transversely or horizontally directed resilient memberor {leaf spring (Figure 10) is located upon the mounting pin adjacentits in nerhead I I8, the spring being iormed -with-a fingerfl22, I24upon each end thereof and disposed in a ccirreSpondingly directed;transverse groove "I26 extending along the inner face o'f-th-diSk-26a.In this casethe mounting annulus I28 g of the guardmember whichsurrounds the mounting pin H4, is provided with a downwardly bent,lateral projection 'I 30 (Figures 7, 3) which isreceived in an inwardlydirected channel; I32 formed-at the intersection of the supportingarmsf28, 30, the pressure oi the leaf spring I20 upon the pin head I I8servingto draw the tit or projection I30 into the socket I32.Accordingly again some little force will be required to push the guardmember to either side iii-order to exposethe spring hook- 86 so that itcan be displaced from abutment with the engag- 'ing u set and ejectedfrom theaperture std. 1 still another construction fora lookingengagement of a lever arm 82a is illustrated in Figures 111-14.The'leverarm adjacent the lo wer edge r the thumb piece 84 is bent intoa u eale134,

the free arm of which I36 extends upward to a correspondingly inverted Uor hook-shaped terminus I38. The-hook extends thruan ape ture I40 nearthe upper margin of the disk 26b and carries a turned down engaging endI 42 overlying the rear face of the disk. By means of a central mountingpin I44 disposed in a transverse opening of the disk 26b and providedwith opposing head members I46, I48 upon its opposite ends, there isrotatablymounteda circular guardmem- 'ber I50, the outer face I52 ofwhich is substan "tially doughnut shaped, with a central depressed areaI54 engagedfby the overlying rivet head I46, and the body of thedoughnut being substantially semi-circular in cross" section. 7

- The fiat rear wall I58 offthe guard member is constructed with as'e'mi an'niilar cut out portion I60; part way around which extends anarcuate engaging finger I62 centered in the open space, coplanar withthe wall I58 and having a free end I64 from which it curves back to itsjunction with the wall proper at I66. Upon insertionof the hook I 42thru 'the'aperture I46 and rotation of the guard member, the guardfinger I62 is adapted to.;pass betweenthe hook end ,I42'and itsinsertion aperture (Figure '12) so asLto hold the hook againstwithdrawal'there- 6'. from. Accordinglythe finger I62 could .be turnedwithin the hook I42 until the latter. abutted against theend wall I66. 2At the free end I64 of the finger. there is a turned up abutment lip orhook I10 (Figure 14). which also engages thespring hook I42 so that. inorder to release the latter at this point,.the thumb piece 84 must firstbe pressed inward and finger I62 then rotated free. Furtherthereisprovided a stop member I12 (Figure 11) mounted upon the face of thestationary disk 26b andex tending into the cutout portion of thedoughnut so as to limit the movement of the latter by contact of thefurther edge I14 of the cutoutthere-i against. In this manner a limit isplaced on the unlocking or counterclockwise turning of the guard I56.Since the natural resilience of the metal lever arm 82a will normallydraw it to the right as viewed in Figure 12, the thumb piece 84: willhave to be pushed inward (i. e. to the left): in both fastening andunfastening the movable hood or its dependent arm 82a.

The manner in which the two parts of th shaving head may be formed fromsheet metal is particularly illustrated in Figures 1'1, 18; Fig.- ure 17shows the stationary portion of the head 22 after it has been stampedout of a flat piece of metal and before ithas been bent. It willbeobserved that the shank 24 and adjacent disk 26 are the only two partswhich will stillremain unbent in the assembled shaving head. However,the engaging lip 90 which is formed in the opening 88 is peened over toprovide more of an abutment for the hook 86 (Figures 3-4). From the diskarea there is also punched out the mounting aperture I16 for the pivotpin 94.

Above the disk 26, the triangular section 32 is cut out to form thesupporting arms 28, 3.0 which may later be bent forward a small amountalong the line I13. At the same time the groove I32 is formed and theslot 36 is made .in the blade-supporting shelf 34 to allow movement ofthe guide fin 14 therealong. g Simultaneously with formation of thelateral wings 38, 46 there is cut away a parallel slot I; I82 betweeneach wing and the adjacent arm so as to provide clearance between thetwo ini their later bent position. A small notch"l84'i's"also now beturned down along theline IBG'and'the wings bent over along the linesI86, I90.

The movable member 60 of the shaving head maybe similarly stamped out ofsheet metal (Figure 18) and subsequently bent for attach ment to thestationary pieceof Figure 1'1. The lever arm 82 is formed with anangularly diverging throat portion I92 which joins the rearwall 62 ofthe hood to the lever arm proper. The rear wall has two more-Or-lessrectangular openings 11, 19 cut out along the midline thereof forreception of the lugs 16, 18 of the inner guide (Figure 5); and inaddition the bearing ears '64 are formed integral therewith, with theiraperitures 63 punched out. The bearing ears are subsequently bent backso as to lie in juxtaposition wtih the apertured wing ends 42 (Figure16) and to receive a hinge pin or rivet 66 jointlytherethru.

At the same time that the movable member .60 is stamped out, the cover61. may have the friction-z-reducingrr-ibs glfl-pressedintoitJf-rombeneath. In the same or a subsequent operation, the head is bentalong the lines 1915, {9 3a and the free end of the leverBZ is then bentinto an en a m hook ztEigure 4 or .12). The thumb piece ea. issolderedlor otherwise attached to the lever as desired.

vrlt willbe observed that 'by the foregoing construction, theconventional'rake-type guard member iis eliminated and its place takenby my frictionareducing roller 59. Altho my invention is particularlyembodiedjn shaving heads for single edged'blades, by-theconstruction ofFigures iil zii however, my roller, and in particularmyinterchangeablerollers of different sizes, can be used also Withshaving heads adaptedto employ-double edged blades. For use with a conventional Gillette-typerazor and blades, there is provided allowerblade-supporting member H33having the usudla-keyed openings 195 for reception of an aligning ribililfiaof the cover member 5%. Each corner of the blade support howeveris provided witha mutually parallel, outward extension 1 {95, which ifstamped out of sheet metal might be termed a ribbon. Each strip 598 isbent sharply upward at 2st to form an abutment for the blade edge 2Msimilarto the notch 54 (Figures 3-4) and is'then curved downward andturned upon itself to form a loop 292. This loop serves as a socket or'i-bearing mounting for the displaceable $3 of my face contacting roller5%]. In addition, transverse, friction reducing ribs 2634 may heprovided along the top surface of the cover to cooperate with therollers in producing a less irritating and smoother shave.
